/* ---------- CRC32 ---------------- */

/**
 * @brief Add support for CRC32
 *
 * Disabling CRC32 will reduce program size (for small micros).
 * If CRC32 is disabled, XOR will be used as the preferred checksum
 * method.
 *
 * Received CRC32'd messages will be accepted without checking.
 *
 * If handshake is used, the peer will detect that CRC32 is not
 * supported here, and should start using XOR.

/* ---------- MALLOC --------------- */

 * @brief Enable malloc if NULL is passed.
 *
 * This lets you malloc() the struct / buffer if you pass NULL
 * to the init functions.
 *
 * Disable malloc to free up memory taken by the malloc routine.
 * If disabled, init funcs will return NULL if NULL is passed
 * as argument.
